l 'G'o'eenes AND 'THE LIKE.

` Appiieationiii-ea January io, 19'2'1. V*serial No. 436,173,

To @ZZ whom t may concern:

BeA it known that we,' FRANK A. IHRCKE and Crans PAn'i'iiNHEiMEinboth citizens of the UnitedStates, and lboth residing at Chicago, inthe county of lCook and'State of Illinois, Vhave invented certain Vnew `and useful Improvements in Goggles and lthe like, of which the following is a specilication.

The present invention 'has to do with certion with goggles for industrial use,` Athe crystals of the goggles become pitted or otherwise injured so that. they can no longer be clearly yseen through.` Ittherefore becomes desirable to replace the-crystals so as to correct this deficiency withoutthe necessity of throwing away the entire goggles themselves. One Vof the Aobjects ,of the present invention is to provide a new and simple form of removable mounting for the crystals so that -the'crystals can be removed or replaced in a very simple inaniier and without the necessity of using special tools.V

lAnother object 'of the invention is 'to provide a goggle construction in which theframes may bemade vof metall instead of from liber or other composition materialas has been customary in the past.- In this connection another A.object is to 'provide a construction of frame which 'can be'very readily stamped out from sheet 'meta-l or from metal tubing by. simple jdieprocesses.

l Another object of `the invention is topro-V vide a removable mounting for the crystals .which may be made entirelyof meta-l, and

which will also serve as a convenient jattac'hment for the nose or bridgeI piece.V

Other objects and uses of the invention will appeal' from a detailed description of the same which consists in the features of construction and combination of parts hereinafter described and claimed..

@to Fig'. 1

In the drawing:

Figure l showsv a front face 'view of a pair OfV goggles embodying the features of the present invention; i

Fig. 2 shows a bottoni view corresponding -3 shows a section taken on the line j'of Fig. l looking in the direction of thefarrows;

Tige s hows av section taken on the linev ell-#4 "o'f Fig. 1 looking in the direction of the- Iarrows F-ig. 5 shows a of Ethe crystal hold-ing rings; 'and Fig. 6 shows a view at right angles to 'Fig 5.

The goggles illustrated in the drawing include two 'frame members l0 and ll of similar construction joined together by a flexible bridge piece 12.' The frame members are provided with straps 1.3 and ll which reach aro-und the 'back of theh-ead of the y wearer in the usual klmanner.

Each of theffra'ine members or 'gua-rds l0 'and' 1l is of generally cylindrical form hav-y ing a flushv frontedge 15 and havin'gits rearedge 16 curved to conform in a general 'way to the face of the wearer. These. guards *are 'conveniently pressed or stamped out of detailed'face view of one n sheet metal-tubing such as aluminumv or v thingauge steel. Furthermore each guard is preferably provided with a series of vent openings i7, and when. these openings are.

provided they may be formed by stamping or pressing the ea-rs 1S outwardlyl during they saine operation in which the guards themselves' are formed. It will be observed that the rear portion of each guard is shown as being deiiect'ed outwardly as comparedr to its front end so as to better conform to the contour of the face of the wearer. This enlargement is vreadily produced during the pressiigor stamping operation. y It is thus .possible to completely fornithe guard from' a 'section 'of sheet `'metal tubi-ng at one oper-k ation which not only produces the vent openings and ears but also gives the guard ioo the desired contour. The rear edge of each lguard maybe covered so as to avoid injury tothe face rof the wearer. This may be "done in any suitable manner as by placing a strip of split tubing` of rubber or the like 19 over the edge, sewing or stitching' the saine to the guard at a number of points 20. y l I serve to hold the Working strips in place at the points where said inner endsv are passed .through the slots 21. in the guard. Each guard is provided with a removable crystal 22. These crystals are preferably of circular form although. in those cases in which the guards are non-circular the crystals may also be made of similar contour.

A crystal carrier 23 is provided for each crystal; each crystal carrier is of the same contour as the crystal which it carries; and its outer peripheral portion is beveled as clearly illustrated so as to securely grip the edge of the crystal. The inner portion of each crystal carrier is formed as a neck adapted to seat snugly Within the correspending guard when in Working position. Each crystal carrier is preferably cut at a convenient point so that the crystal can be inserted or removed from it by spreading open as shown in Fig. 5; but the parts are so proportioned that when the yneclr is seated into the guard the carrier will be retained against such expansion and the crystal will therefore be prevented from coming ont of it.

At one point, generally adjacent to the split. the crystal carrier is provided With an ear Qef. llhen the crystal carrier is set into place in the guard, this ear passes through a slot in the inner side of the guard as clearly shown in Fig. el; and the ear then serves as a convenient element to which is attached the bridge piece l2. The crystal carrier thus serves not only the function of supporting the crystal, butl also of providing an attachment for the bridge piece.

The opposite side of the crystal carrier may be secured Within the guard in any suitable manner as by means of a spring catch 25 secured to the inner face of the guard and engaging a slot 26 in the crystal carrier.

While We have herein shown and described only a single embodiment of our invention, still We do not limit ourselves to said embodiment except as We may do so 'in the claims.

To claim:

l. il. pair of goggles c nnpiising in cornbinition a pair or cylindrical eye guards eac comprising al section of metal tubing having its inner edge shaped to conform ally to the contour of thelface of the :er and having its outer edge lying at r' 'ht angles to its axis, a strip of protecting material laid over said inner edge, stitches securing the same to the guard and passing through perforations in the metal of the guard, a crystal carrier for each guard,each crystal carrier being of split circular form and having its outer portion recessed for the accommodation of the edge of a crystal and havingits inner portion of cylindrical form and adapted to seat `snugly'intothe outer end portion of the guard, there being` a slotted perforation at the inner side of each guard adjacent to the position of the crystal carrier, a lug on the crystal carrier passing through said slotted perforation, a bridge piece joining together the lugs of the two crystal carriers and independent locking means for securing each crystal carrier Witl1- in the corresponding guard at a point opposite to its lug, substantially as described.

2. A pair of goggles comprising in coinbination a pair of cylindrical eye guards each comprising a section of metal tubing having its inner edge shaped toconform generally to the contour of the face of the ivearerand having its outer edge lying atv right angles to its axis, a crystal carrier for each guard, eachV crystal carrier being` of split circular form and having kits outer portion recessed for the accommodationv of the edge of a crystal and having its inner portion of cylindrical form and adapted to seat snuglv into the outer end portion of the lguard, there being a perforation. at the inner side of each guard adjacent to the position of the crystal carrier, a lug on the crystal carrier passing through said *perforation7 a bridge piece joining together the lugs of the two crystal carriers and independent locking means for securing each crystal vcarrier Within the corresponding guard at a point opposite to its lug, substantially as dey scribed. l

3. A pair of goggles comprising in combination a pair of cylindrical eye guardsr each comprising a section of metal tubing having its inner edge shaped to conform generally to the contour of the face of thev wearer and having its outer edge lyingat right angles to its axis, a crystal carrier for each guard, each crystal carrier being of y split circular forin'andrhaving its outer portion adapted for the accommodation of the edge of a crystal `and having its inner portion of cylindrical form and adapted to seatr snugly into the outer end portions of the guard, there being perforat-ious at the inner side of each guard adjacent to the position. of thecrystal carrier, a lug on each crystal carrier passing through its perforation, a bridge piece oining together the lugs of the tivo crystal carriers, substantially as described.
